It isn't just an issue of how smooth the graphics look and whether someone can notice the difference.GundamSentinel said:Unless you have medical reasons or are playing competitive games that really require twitch reactions, I really don't see the point of insisting on 60fps.
Input lag is often worse for 30fps games because it's a fixed number of frames between when the action is initiated by the user and when it shows up on the screen. It makes sense - why would a game process input at 60fps if it's only going to update the game state and graphics at 30fps?
Of course, input lag is another issue that many users claim not to notice unless it's really bad.
